A kind of which includes high-power semiconductor laser therapeutic equipment is designed beam path, current source and protective circuit and constant temperature control unit. By comparing and analyzing the effects of GaAlAs, InGaAs and Nd:YAG lasers in medicine, InGaAs high-power semiconductor laser therapeutic equipment with output wavelength at 980 nm is used as effective light source, 670 nm semiconductor laser as aiming beam. This equipment has the highest power of 3 W, with such virtues as high output power, small volume and long life span, and has a very good prospect of application to tumor, ear-nose-throat department and gynecology.
